I forpield by a seiliei of pelescopicbtubes ra ity: This invention relates to an im rover anc tiese treats y tie cross ars e combined window rest and escape ladder ladder is held by the chain. If required the which can be put on and taken off the windevice may be arranged in such a manner dow, and. consists in the arrangement of that the ladder ofahigher story maybe drawn same in such a manner that the longitudinal out so as to reach the window of the story unbeams of the ladder consist of a number of derneath with which it can be'connected,and telescopic parts carrying the cross bars of which forms further connection to a still tread between them, by means of which lower story or the ground. parts the ladder can be collapsed as well as extended to any required length. I I will now describe my invention with ref- I erence to the accompanying drawings, in

step may be varied according to requirements; for

instance five tubes may be arranged between the outer tubes 0 instead of which, three (5, a, b) as shown in the drawings.

Figure 1 shows the arrangement in its use Having now particularly described and asas a window rest. Fig. 2 shows same in its Figs. 3 and 4 are views of details, partly in section.

The arrangement as shown in the drawings 1. The combination with the building of a comprises two parallel sides placed horizonladder approximately the length of the height tally along the window, said sides consisting of a story, the stiles of which are made in of a number of telescopic tubes a, b, c. telescopic sections, sections of one stile being Each pair of oppositely arranged tubes (1 and connected to corresponding sections of the c of the longitudinal sides is held firmly conother stile by rungs, the stiles having at each nected by means of cross bars (Z. The two end blocks adapted to engage the window outer tubes 0 are provided with flanges e frame and secure the (Figs. 3, 4), screwed to them, by means of transversely thereof, which the device is guided and supported in guard. grooves f (Figs. 1 & 2) arranged in the window 2.
